Subject: [PATCH v2 0/2] Add ExynosAutov920 hsi0 support to exynos-sysreg
Date: Thu, 12 Feb 2026 17:21:05 +0900 [thread overview]
Message-ID: <20260212082105.1878720-4-sh86.bae@samsung.com> (raw)
In-Reply-To: <20260212082105.1878720-1-sh86.bae@samsung.com>
The ExynosAutov920 SoC includes a PCIe IP and a hsi0 register block that
is mapped in the exynos-sysreg.
To manage PCIe PHY power, configure the PCIe PLL, and set the device direction,
the hsi0 registers need to be defined in exynos-sysreg.
This patch must be applied before the ExynosAutov920 PCIe PHY is enabled.
